Methods

connectsWithRoot()

Source:
Inherited From:

Goes up the hierarchy and determines if this CatalogMember is connected with the root in terria.catalog, or whether it's part of a disconnected sub-tree.

enableWithParents()

Source:
Inherited From:

"Enables" this catalog member in a way that makes sense for its implementation (e.g. isEnabled for items, isOpen for groups, and all its parents and ancestors in the tree.

findInfoSection(sectionName) → {Object}

Source:
Inherited From:

Finds an CatalogMember#info section by name.

Parameters:
Name Type Description
sectionName String

The name of the section to find.
Returns:

The section, or undefined if no section with that name exists.

Type
Object

getParameterValues() → {Object}

Source:
Inherited From:

Gets the current parameters to this function.

Returns:

An object with a property for each parameter. The property name is the id of the parameter and the property value is the value of that parameter.

Type
Object

invoke() → {Promise}

Source:
Overrides:

Invoke the WPS function with the provided parameterValues.

Returns:
Type
Promise

load() → {Promise}

Source:
Inherited From:

Loads this function, if it's not already loaded. It is safe to call this method multiple times. The CatalogFunction#isLoading flag will be set while the load is in progress. Derived classes should implement CatalogFunction#_load to perform the actual loading for the function. Derived classes may optionally implement CatalogFunction#_getValuesThatInfluenceLoad to provide an array containing the current value of all properties that influence this function's load process. Each time that CatalogFunction#load is invoked, these values are checked against the list of values returned last time, and CatalogFunction#_load is invoked again if they are different. If CatalogFunction#_getValuesThatInfluenceLoad is undefined or returns an empty array, CatalogFunction#_load will only be invoked once, no matter how many times CatalogFunction#load is invoked.

Returns:

A promise that resolves when the load is complete, or undefined if the function is already loaded.

Type
Promise

serializeToJson(optionsopt) → {Object}

Source:
Inherited From:

Serializes the data item to JSON.

Parameters:
Name Type Attributes Description
options Object <optional>

Object with the following properties:

Properties
Name Type Attributes Description
propertyFilter function <optional>

Filter function that will be executed to determine whether a property should be serialized.
itemFilter function <optional>

Returns:

The serialized JSON object-literal.

Type
Object

setParameterValues(parameterValues)

Source:
Inherited From:

Sets the current parameters to this function.

Parameters:
Name Type Description
parameterValues Object

An object describing the parameters to set and their values. Each property name in this object corresponds to the id of a parameter, and the value of that property is the new value for the parameter. If there is no parameter corresponding to a property in this object, that property is silently ignored.

updateFromJson(json, optionsopt) → {Promise}

Source:
Inherited From:

Updates the catalog member from a JSON object-literal description of it. Existing collections with the same name as a collection in the JSON description are updated. If the description contains a collection with a name that does not yet exist, it is created. Because parts of the update may happen asynchronously, this method returns at Promise that will resolve when the update is completely done.

Parameters:
Name Type Attributes Description
json Object

The JSON description. The JSON should be in the form of an object literal, not a string.
options Object <optional>

Object with the following properties:

true to only update existing items and never create new ones, or false is new items may be created by this update.

If specified, sets the CatalogMember#isUserSupplied property of updated catalog members to the given value. If not specified, the property is left unchanged.
Returns:

A promise that resolves when the update is complete.

Type
Promise
